To complain a bit.Why did Google have to use Kit Kat as a symbol / Name for their new platform...It is sad as Nestle is one evil motherfucker of a company!

Anyway that said if you did not know and you are looking for a new device the Google Nexus series with Android 4.2 is the best device you can get if latency is something that bothers you and this could be an interesting phone as it is cheaper than the other high end phones and being made by Google all improvements when it comes to audio will be in their devices

( at least before any other company).

Here is what is new regarding Audio and Android 4.4 (Kit Kat)------------------------------------------------------------------------------------------------------------------------------------------------Audio Tunneling to DSP For high-performance, lower-power audio playback, Android 4.4 adds platform support for audio tunneling to a digital signal processor (DSP) in the device chipset. With tunneling, audio decoding and output effects are off-loaded to the DSP, waking the application processor less often and using less battery.Audio tunneling can dramatically improve battery life for use-cases such as listening to music over a headset with the screen off. For example, with audio tunneling, Nexus 5 offers a total off-network audio playback time of up to 60 hours, an increase of over 50% over non-tunneled audio.Media applications can take advantage of audio tunneling on supported devices without needing to modify code. The system applies tunneling to optimize audio playback whenever it's available on the device.Visualization of how the Loudness Enhancer effect can make speech content more audible.Audio tunneling requires support in the device hardware. Currently audio tunneling is available on Nexus 5 and we're working with our chipset partners to make it available on more devices as soon as possible.Audio monitoring Apps can use new monitoring tools in the Visualizer effect to get updates on the peak and RMS levels of any currently playing audio on the device. For example, you could use this creatively in music visualizers or to implement playback metering in a media player.Loudness enhancer Media playback applications can increase the loudness of spoken content by using the new Loudness Enhancer effect, which acts as compressor with time constants that are specifically tuned for speech.Audio timestamps for improved AV sync The audio framework can now report presentation timestamps from the audio output HAL to applications, for better audio-video synchronization. Audio timestamps let your app determine when a specific audio frame will be (or was) presented off-device to the user; you can use the timestamp information to more accurately synchronize audio with video frames.Wi-Fi CERTIFIED Miracast™Android 4.4 devices can now be certified to the Wi-Fi Alliance Wi-Fi Display Specification as Miracast compatible. To help with testing, a new Wireless Display developer option exposes advanced configuration controls and settings for Wireless Display certification. You can access the option at Settings > Developer options > Wireless display certification. Nexus 5 is a Miracast certified wireless display device.------------------------------------------------------------------------------------------------------------------------------------------------If you want know more about the other functions as a developer
